Abstract A current control method with Load current injection based on Grounding type step-down Cuk converter is proposed in this paper, the main circuit can have lower ripple step-down conversion while easily driven. This control method can effectively improve the dynamic response capability of the system. This paper introduces the working principle of the step-down converter briefly and the fast dynamic control method, then verifies the control method has faster dynamic response capability than traditional current-mode control through Pspice simulation and prototype experiment.
